Use dials or twist-turn knobs to alter settings, such as brightness or contrast. These settings cannot be saved for future recall but are ideal for quick access to certain functions that users like to change frequently.

LCD monitors with an analog interface can accept an analog video signal using standard RGB connectors for personal computers, in the same way as a CRT monitor. The analog signal is then converted into the digital signal used for display on a LCD panel. LCD monitors with only a digital interface require a dedicated graphics adapter and connectors, which come in varied formats.

(Analog/Digital converter) A device that converts continuously varying analog signals from instruments that monitor such conditions as movement, temperature, sound, etc., into binary code for the computer. It may be contained on a single chip or can be one circuit within a chip.

(American National Standard for Human Factors Engineering of Visual Display Terminal Workstations). Organization that produces publications concerning the ergonomics of monitors.

A treated glass panel that is placed over a monitor screen to reduce glare.  

A monitor screen that is treated to reduce glare from light sources. Non-glare CRTs often use a coating baked onto the screen at the time of manufacture, which provides a significant reduction in glare; however, LCD screens may completely eliminate it.

The ratio of the width of the picture to the height. For most current monitors, this ratio is 4:3. For HDTV, the ratio will be 16:9 or 16:10.

Saves the time of manually tracking monitors across the network. Allows the retrieval of key asset-tracking information, such as monitor make, model, and serial number, when the monitor is used with a Compaq PC supporting Intelligent Manageability and appropriate network software. This information is especially useful for network administrators.

A special one-touch Auto Adjust button allows users to quickly set the display panel to match their preferences and provides users with excellent front-of-screen performance and minimal set up.

Same as Auto Adjust.

An LCD screen that has its own light source from the back of the screen, making the background brighter and characters appear sharper.

The speed, measured in megahertz, at which the data can be accepted from the CPU/graphics adapter to the monitor. A greater speed means that higher resolutions can be shown with more brightness and clarity.

The light level on a display screen.

Defines the whiteness of the white on the screen. Variations are measured in degrees Kelvin. Natural colors used in life-like images, such as people or landscapes, look more true to life when displayed at a color temperature of 6500K. Black text on a white page is better represented by a color temperature of 9300K.

Color matching refers to the process of accurate duplication of colors between the display and either input (like a VGA card) or output (like a printer). An LCD display with color matching stores color-related parameters in special memory called EEPROM, and uses this data for optimization, providing benefits such as WYSIWYG printing and faithful representation of Web graphics.
